Opus 4

Opus Series

With a refined case design inspired by the Harry Winston Premier, the Opus 4, at first glance appears to have a more traditional take on fine watchmaking. Looking closer, however, reveals an unexpected and exceptional surprise: the watch is completely reversible. One face is technical, featuring two of fine watchmaking’s most revered complications: a tourbillon and a minute repeater that uses a cathedral-type chime.

Rotating the case reveals the other, more poetic side, featuring a large, delicately engraved moon-phase and date on the perimeter of the dial. The intricate movement has 423-parts, including 40 jewels.
